application a... January 20, 1909. seriai'no. 413,3.

Be it known that I, Riemann S. BRYANT, a citizen of the United States, residing at Columbus, in the county of Franklin and Stateof Ohio, have invented certain new and useful Improvements in Tire-Fasten ing Devices,

which the following is. a specification, Y

My invention relates to improvements inv tire-fastening devices, and consists especially of they provision of a tlre-retalnmg flange having extensions formed on its ends, and" readily detachable gripping means applied to said extensions for the purpose of drawing the fastening device into snug and secure engagement with the rim of a vehicle wheel, whereby a tire is securely held in position thereon.

Specifically, to a device inclu ing shaped member adapte to be positioned u'pon extensions formed on the ends of an annular tire-retaining flange to inclose and embrace the said extensions; means are carried by the cup member to engage one of the extensions positively, and to engage the others adjustably to bring them into snug abutting relation'andto grip the tire-retaining flange firmly upon the rim.

A preferred form of embodiment of my invention is shown in the drawings, which are hereto attached and hereby made a part of this specification, in which- Figure 1 is a side view of a portion of a vehicle wheel having my device thereon in place; Fig. 2 is a ortion of the circumference of a wheel slowing the tire-retaining flange, and the retainingdevice in vertical transverse section; Fig. 3 is a vertical transverse section through the rim and tire in place, taken at the end of the detachable tire-retaining flange; Fig. 4. is a vertical transverse section through the cup-shaped member detached from the tire-retaining flange disclosing the lug and the clamping -or grippin device; Fig. 5 shows an optional method 0 locking together the extensions on the tire-retaining flange. Fig. 6 is a top plan view of the rim showing the recess or cutout therein.

Referring to the drawings in which the 'same numeral indicates the same part the resent invention relates. referably a cup tachable tire-retaining flange being shown ati5. At its ends thedetachable tire retaing g a ge 5 is provided with extgnsinns- 6H and 7 which are preferably formedwvi h the beveled faces 8 and 9; the extensions maybe locked together ina numberof, ways, one'of' which is shown in'Figl 2 and another in Fig.

5. Referring to Fig. 2',"it is seen that the extension 7 has the-projecting lip 10 adapted .to.underlie the extension 6, and so long as the extension 6 is maintained in its' proper position, it is readily seen that the extension will be held in place. In positioning the tire-retalning flange 5, the extension is placed in the cut-out 11 of the rim against the shoulder 13, and the flange is then posi-' tioned in the channel 23, around the periphery of the rim body, until the extension 6 is brought into place against the shoulder 12 of the cut-out 11. It is understood that the tire has first been placed upon the rim face tobe'engaged by the flange 3.

The extension 6 has -a transverse recess 14 formed therein, the cup-shaped member 15 has the lu 16 located therein, either cast or inserted in a preferred manner, and this lug 16 is adapted to be inserted in the recess 14, when the member 15 is positioned. The cup-shaped member 15 is adapted to inclose or embrace the extensions 6 and' 7, the lug 16 being inserted in the reces' or groove 14 the set screw 17 is inserted through the opening 18 formed in said member 15, the inner end of said screw being adapted to enter and engage the depression or recess 18 formed in the extension 7.

As the screw 16 is turned, the extensions 6.

and 7 are drawn .together, it bein stood that before the pressure 0 the set screw is thus applied, the ends of the tireret'aining flange are somewhat se arated. In this manner the tire-retaining ange is underseated snugly and securely in the channel such away that dust and dirt are e ectually excluded; this preserves the parts and also tends to make them more easily manipulated. It is also seen that thereby the ends of the extensions are protected from violence and possible injury due to collisi ns with objects, or possible injury from any other source during the operation of the vehicle.

In Fig. 5 I have shown an optional form of locking together the extensions on the tire-retaining flange to prevent movement of the same upon each other, and in this figure the extensions are formed with grooves and 21 adapted to be brought into register, whereupon the key 22 may be inserte when this has been done, neither of the extensions 6 and 7 is free to move in a radial direction without the other. The cup member 15 is then placed on the extensions and secured as above stated.

The specific construction illustrated in the drawings and herein described is a preferred embodiment of my invention, but I do not desire to be limited to such consions formed at its struction, but desire to claimall modifica- 1 tions thereof which are within the spirit of my invention.

What I claim is:

A. tire-retaining device comprising a divided tire-retaimng flange having extenends, a rim constructed to receive said extensions, one of said extensions having a depression formed thereon, a cup-shaped member having a lug adapted to engage said depression whereby said cup-shaped member may be secured on said extension in a position to embrace said extensions and grip'the same together and protect them, means for preventin outward movement of said extensions, an a screw carried by said cup-shaped member for forcing said extensions toward each other whereby said tire-retaining flange is securely positioned upon the rim.

In testimony whereof I aflix my signature in the presence of two witnesses.
